Lay awake for hours last night. Woke up around 4:50, scratched at an annoyance (less than an itch) on my leg and accidentally mauled a spider. Poor creep - abysmally bad timing on its part.
Couldn't go back to sleep, so I played SMAC for a while. And now it's late enough where I might as well start my day. Two, maybe three hours of sleep. This will not go well.
